【 摘 要 】

Groove type is critical to the compactness of fibrous ring in groove and cohesion between fibers. The effect of groove type to high speed airflow during rotor spun yarn spinning process was investigated. Airflow speed and static pressure of G, T, U and S grooves of the 36 mm diameter rotor were studied by Fluent Software respectively. The results showed that under the same conditions, speeds in four slotted size were G>T>U>S within the range from 0° to 360° in groove. At 0° and 360° positions, the static pressures were G>S>U>T. While for the rest of angle position, the static pressures were S>U>T>G. Taking T slot as example, static pressures of the rotors were between -7330.80 Pa and -13719.63 Pa. High speed airflows were divided into two streams as soon as they enter into the inner wall of rotor (0opoint), one clockwise and one reverse direction, which joined together at point of 180o. This phenomenon gives light to understand fiber strands stretch and twisting as yarn in rotor which can be used to optimize spinning parameters during spinning and design new rotor type.
